I explained that if I kept the letter I might be suspected of an intention of stealing it, whereas directly there was any inquiry, he could certify that I had left it in his charge. He seemed to be satisfied and asked me to come into his study for a moment. The man in the lane was probably satisfied, too. I had stood three paces from the table-lamp all the time, waving the letter about as I talked, and casting a bold shadow on the linen blind!

The first thing that struck me as I entered the doctor's study was that the French windows, which opened on a sheltered lawn, were open. I acted accordingly.

"You see," said Dr. Stuart, "I am enclosing your letter in this big envelope which I am sealing."

"Yes, sir," I replied, standing at some distance from him, so that he had to speak loudly. "And would you mind addressing it to the Lost Property Office."

"Not at all," said he, and did as I suggested. "If not reclaimed within a reasonable time, it will be sent to Scotland Yard."

I edged nearer to the open window.

"If it is not reclaimed," I said loudly, "it goes to Scotland Yard—yes."

"Meanwhile," concluded the doctor, "I am locking it in this private drawer in my bureau."

"It is locked in your bureau. Very good."
